自定义DNS解析
在corefile 中添加域名信息
apiVersion: v1 data: Corefile: | .:53 { errors health { lameduck 5s } ready hosts { 192.78.95.36 ttttt.com.cn fallthrough } kubernetes cluster2.local. in-addr.arpa ip6.arpa { pods insecure fallthrough in-addr.arpa ip6.arpa ttl 30 } prometheus :9153 forward . /etc/resolv.conf { max_concurrent 1000 } cache 30 loop reload loadbalance } kind: ConfigMap
fallthrough表示在hosts找不到解析的域名时,传递给CoreDNS的下一个插件,避免集群内部域名解析失败。
